Modeling DRX for D2D Communication
IEEE Internet of Things Journal, 2021Discontinuous reception (DRX) has been included in 4G-LTE as the main power saving mechanism for user equipment (UE). However, the existing 3-state DRX model is not sufficient for new use cases introduced by 4G and 5G. For example, the device discovery process in device to device (D2D) communication has a significant impact on delay and power ...

Feasible D2D communication distance in D2D-enabled cellular networks
2014 IEEE International Conference on Communication Systems, 2014In D2D-enabled cellular networks, data communications between user equipments (UEs) can be completed by two modes: the cellular mode and the D2D mode where UEs bypass the base station and directly communicate with each other. Usually the transmission mode is selected based on the distance between the UEs.

IOT based efficient D2D communication
2018 Moscow Workshop on Electronic and Networking Technologies (MWENT), 2018Drastic increase in number of users have put cellular operators in trouble. Researchers found the way in internet of things (IoT). Device to device communication(D2D) is a basic part of IoT. In this paper, a device is installed between cellular and device users that will act as a gate between the two.

D2D CSI feedback for D2D aided massive MIMO communications
2016 IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM), 2016We consider fast fading massive MIMO systems in Frequency Division Duplex (FDD) mode and propose a communication scheme based on Device-to-Device (D2D) cooperation and statistical channel state information (CSI) feedback. User terminals (UT) are conveniently clustered and cooperate within a cluster to create a virtual MIMO at a target UT via D2D ...

D2D Covert Communications With Safety Area
IEEE Systems Journal, 2021In this article, we investigate device-to-device (D2D) relay enabled covert communications. Safety zone is employed to isolate the eavesdroppers from the transmitters and receivers. Different from majority of the existing studies considering fixed relays, dynamic relay selection is first considered for covert communications in this article ...
